Device and method for controlling ignition timing of internal combustion engine |
摘要 |
An engine ECU executes a program that includes: calculating a median value and a standard deviation based on a calculated value based on the detected vibration of the engine; and subtracting a product of the standard deviation and a coefficient from the median value to calculate a magnitude of mechanical vibration specific to the engine. Knocking determination is carried out by comparing a knock magnitude calculated by dividing the magnitude value of the peak magnitude of the detected vibration of the engine by the magnitude of mechanical vibration specific to the engine with a predetermined determination value. Based on the knocking determination result, ignition timing of the engine is controlled.
